Since its discovery by a teenager in 1859, thousands of specimens of lustrous black tourmaline crystals from Pierrepont, New York, have found their way into both museum and private mineral collections worldwide. Pierrepont is a classic American mineral locality and a popular site for field collecting, and the discovery of new collecting sites there in the past decade has only enhanced its importance. Yet no detailed scientific research has been published until now. The six authors represent a team with comprehensive skills to tackle this study, which covers the locality's history, geology, and mineralogy. The origin of the mineralization, the true nature of the black tourmaline, and the extensive suite of accessory minerals are presented in detail. The authors also resolve identification questions about the tourmaline and its many accessory minerals.

Tourmaline group minerals have graced the cabinets of mineral collectors and museums for untold generations. Their colors and color patterns, along with their diverse shapes and associations, have assured their role as exqui site showpieces. Their workability and durability have, in addition, made them favorites among connoisseurs of colored gemstones. Tourmalines, however, are much more than exquisite showpieces and beautiful gemstones. Their diverse crystal forms and unique structure, their variable chemical compositions, their intriguing physical properties, and their widespread occurrence in nearly all kinds of rocks have long attracted the attention of scientists from several disciplines. Furthermore, they have several potential uses in science and industry. From an historical standpoint: Tourmaline is possibly the "Lyngurium" -green at one end, light colored at the other-that Theophrastus (ca.315 B.C.) described in On Stones, the first known book about minerals. Tourma line is one of the minerals thought to have been used as a "sunstone" navigation compass by Vikings during the eighth, ninth, and tenth centuries.

Quartz is prized by both mineral collectors and lapidary artists. Over 130 vivid photographs of these beautiful minerals are presented to show each mineral in its geological context. Superb examples are found in diverse geological settings from pegmatites to Alpine clefts and hydrothermal veins. The silica minerals are chemically simple, yet structurally complicated. Several high temperature and high pressure polymorphs are known. In addition to the polymorphs of silica, this book treats related minerals, including: lechatelierite, opal, and two natural clathrates, chibaite and melanophlogite. After a brief introduction, the general treatment explains the chemistry and taxonomy of the group. A section on their formation and geochemistry describes the kinds of environments where these minerals are formed. Then, entries for each mineral provide locality information and full-color photos so that collectors can see what good specimens look like and which minerals one might expect to find in association with them.

The axinite group of rock-formed minerals is well known to collectors through the spectacularly sharp crystals collected in quantity at Dal'negorsk and Puiva in Russia and at Tomas and other localities in Pakistan. Axinites are occasionally cut as gems. This concise monograph provides an up-to-date review of the group, incorporating recent changes to the names of three axinite species. The book is illustrated with over 90 full-color photographs of representative specimens. After a brief introduction, the text provides an explanation of the chemistry and taxonomy of the group and an illustration of the crystal structure and morphologies of real crystals. Detailed entries for each mineral provide information on notable localities and full-color photos wherever possible, so that readers can see what good specimens look like and which minerals one might expect to find in association with axinites. This book is a must for mineral collectors everywhere.

Over 115 striking color photos display pyroxene group minerals in all their forms and colors. This group of rock-forming minerals is best known to collectors through well-formed diopside crystals from many localities, including in Canada, the northeastern United States, the Alpine regions of Europe, and through the gem-quality spodumene found in pegmatites from California to Pakistan. Spectacular recent finds of diopside in Pakistan, hedenbergite at Dal'negorsk, Russia, and aegirine in Malawi have added to the interest in this mineral group. Several pyroxene species are important in the gem trade, including colored varieties of spodumene (kunzite and hiddenite), green "chrome" diopside, and jadeite, one of the two true jade minerals. The informative text provides an introduction to their formation and geochemistry and a detailed entry for each mineral, including color reference photos. This book is essential for every mineral collector.
